Motherboard Expansion Slots and RAM Types
Motherboard Expansion Slots
Expansion slots on motherboards allow additional components, such as video cards, sound cards, or network cards, to be added to enhance the computer’s functionality. These slots vary in type and capacity depending on the motherboard’s design and format (e.g., full ATX or micro-ATX). Common types of expansion slots include:
- ISA (Industry Standard Architecture): Older 8 or 16-bit slots used primarily before 1997, often black and with two parts (shorter and longer). Phased
